HVAC Temperature Sensor

As one of the leading industrial sensor suppliers, TOPOSwas founded in 2003. In the beginning, it is the first company that can mass-produce the most stable glass-bead type thermistors. Ten years sharpening a sword, TOPOS becoming the high-tech company in this field. Our main products are NTC chips, NTC type thermistors (negative thermistors), Temperature sensors, Humidity/Gas sensors, widely applied in the green-car industry, smart home appliances, electronic thermometer, ... etc.

Details

Material: nylon shell/sheathed wire

Applicable temperature range：-30~125℃

Output signal: analog signal output

Advantages

1. The outside air temperature sensor hvacis a radial lead single-ended glass package thermistor
2. Good stability and high reliability
3. Wide resistance range: 2~500KΩ
4. High resistance and B value accuracy
5. Glass packagecan be used under harsh conditions such as high temperature and high humidity
6. Small size, sturdy structure, easy for automatic installation
7. Operating temperature range -30~+125℃
8. Fast heat induction and high sensitivity

Applicatio

Hvac temp sensor.

General parameters

ResistanceR25℃：	5K	10K	15K	20K	50K	100K	200K
B value(R25/R50)	3380	3950	3470	4200	3977	4100	4200
Tolerance	1%	2%	3%	5%

Note: What is the B value:

A material constant that describes the resistance-temperature relationship. The value of B can reflect the scale of resistance to temperature change between two specific temperatures. As the hvac temperature probechanges, the resistance value of a product with a large B value under the same conditions changes more, that is to say, it is more sensitive.
